I have managed to complete a tutorial on c++ and have 1 year experience.
I also did very basic WinAPI stuff, and I'm now on C++/MFC with Jeff Prosise's second edition Programming Windows with MFC.
Now I want to know how I can start making games. Shoud I just move on to a graphics library? Or continue?
Any advice/tip/suggestion, mann anything that would be helpful is appreciated,
You can either continue to learn C++/MFC* or begin learning a graphics library. Either way, you need to learn both of them to develop games. If you're comfortable with the advanced C++ concepts such as polymorphism and DMA, I would suggest shifting your focus onto a graphics library.
*I don't know why you would want to learn C++/MFC, but it's your choice after all.
